Sky Sports understands there is interest from the continent in the duo, who both joined Rangers last summer, but it seems that the pair could be heading back to the Premier League.
Interest in former Marseille star Mbia is strong, and his ability to play in defence or midfield looks to be a major draw, with Arsenal, Aston Villa and Swansea City all believed to be considering moves for the Cameroon international.
Sources close to the player have confirmed that the 27-year-old is settled in England and would relish the chance to stay in the Premier League, although the prospect of playing in the Championship with QPR is not thought to appeal.
With Mbia one of the higher earners, it is unlikely that QPR will stand in his way if interest should become concrete, and the same is believed to be the case for Diakite.
Fulham and Stoke, where Mark Hughes, who signed Diakite for QPR, is now manager, are both understood to be keeping close tabs on his situation and could be set to make offers for the 24-year-old.
